When you're lying in bed trying desperately to fall asleep, your mind may seem like your worst enemy, keeping you awake. If you keep your mind focused, however, such as on numbers, you may fall asleep faster. Redditor JarlOfBacon suggests counting the Fibonacci sequence.

The Fibonacci sequence is a series of numbers starting with 0 and 1 and then each subsequent number is the sum of the previous two.

I use numbers sometimes to fall asleep too and cure my monkey brain sleep problem, but just regular counting (no actual math)—visualizing the numbers starting at 100 and counting backwards, then letting the numbers fall off at around 80-something.
